[Peripheral Primitive Neuroectodermal Tumor of the Small Bowel Mesentery - Report of a Case].

Introduction: Primitive neuroectodermal tumor or Ewing's sarcoma is a tumor of undifferentiated small round cells that arise from the soft tissues, and is believed to be of neural origin. It occurs most often in children, followed by adolescents and young adults.

Case Outline: A case of a 24-year-old patient with ulcerostenosans Ewing's sarcoma of the initial part of the small intestine is presented in our paper.

[Streptococcus bovis endocarditis as a sign of colon cancer: case report].

Introduction: Streptococcus bovis is labeled in the literature as a cause of bacteremia and endocarditis, which are often associated with gastrointestinal malignancy.

Case Outline: In our paper we present a patient with endocarditis induced by Streptococcus bovis who was also, after completed cardiologic examination and treatment, diagnosed colon cancer in situ by targeted endoscopy. Owing to the timely diagnosis, and after successful cardiologic surgery with implantation of an artificial aortic valve, patient underwent surgery of the colon, and is now asymptomatic and in good health.

[Surgical anatomy of the initial segment of the lateral circumflex femoral artery].

Introduction: The lateral circumflex femoral artery usually originates from the lateral side of the initial part of the deep femoral artery, or less frequently from the femoral artery. If it is a branch of the femoral artery, it arises directly above the point of origin of the deep femoral artery. The aim of this study was to determine the origin of the lateral circumflex femoral artery, its origin distance from the midpoint of the inguinal ligament and the topographical relations of the origin, which have a great significance in clinical work.

Origin of the medial circumflex femoral artery--a cadaver study.

Aim: To determine the pattern of origin of medial circumflex femoral artery (MCFA), its origin distance from the midpoint of the inguinal ligament and the topographical relations of the origin, which have great significance in clinical work.

Methods: Dissections on the autopsy group of 42 thighs were performed, and anatomical relationships of MCFA was analyzed. All data were entered into a scheme of the protocol which was designed for this research containing the case number, age and sex, side, topographical-anatomical relations of MCFA, artery dimensions and variations, and the distance between the place of origin of MCFA and the midpoint of the inguinal ligament.

Preoperative evaluation in the era of laparoscopic surgery.

To confirm the importance of preoperative evaluation of a patient's health state, to reduce perioperative morbidity and mortality after laparoscopic surgery. A total number of 1,070 patients were selected into groups based on a type of intervention, gender, ASA and NYHA classification. The most common laparoscopic procedure that was performed was cholecystectomy in 920 (86%) patients.

Laparoscopic body-tail pancreatic resection for insulinoma.

Introduction: Insulinomas are the most common endocrine tumours of the pancreas. They are more frequent in females, and they are commonly less than 2 cm in diameter. If conservative treatment of typical clinical symptoms fails, detailed diagnostic procedures are necessary and surgical treatment is indicated.

Intraoperative air testing of colorectal anastomoses.

Introduction: Intraoperative anastomotic air testing of stapled colorectal anastomosis is performed by filling the pelvis with saline solution and insufflating the rectum with air through a sigmoidoscope. The presence of air bubbles indicates anastomotic leaks which are resolved during surgery.

Objective: The aim of this prospective, randomized study was to perform a comparative analysis regarding the number of anastomotic dehiscences in patients checked by air leak testing and in the control group without air testing.

Adenomyomatosis of the gallbladder--case report.

Adenomyomatosis of the gallbladder is a benign, mostly asymptomatic condition of an unknown aetiology. Hyperplastic changes in the gallbladder wall cause an overgrowth of the mucosa, thickening of the muscular wall, and formation of intramural diverticula or sinus tracts termed Rokitansky-Aschoff sinuses. Adenomyomatosis is divided on general, segmental and localised.

[Thoracoabdominal teratoma--rare location].

Introduction: Teratomas are tumours derived from pluripotent germ cells. They appear most frequently on ovaries. However, other locations are also possible: testicles, retroperitoneum, stomach, neck, and bottom of the mouth cavity.

[Complications in laparoscopic surgery].

The development of technology and improvement of laparoscopic equipment enhanced expansion laparoscopic surgeries. Various operations performed using classical operative approach are nowadays done laparoscopic technique. The expansion of the repertoire, the performance of most complicated surgical procedures and increase in the number of laparoscopic interventions result in the increased number of intraoperative and postoperative complications.

[A case of choledochal cyst complicated by biliary peritonitis].

Introduction: Choledochal cyst is a rare congenital malformation of the extrahepatic bile ducts. Its incidence varies among different populations, but it is highest in North East Asia. It is most frequent in childhood, and very rare in adults.

Harmonic Scalpel hemorrhoidectomy: a painless procedure?

Since the surgical treatment of hemorrhoidal disease has been characterized by intense postoperative pain, recent studies have tried to modify the standard Milligan-Morgans technique. The up-to-date literature, in the experience of authors, has confirmed that the new method of Harmonic Scalpel hemorrhoidectomy reduces postoperative pain. The aim of our study was to statistically evaluate, based on our experience, the efficacy of this surgical approach in terms of reducing postoperative pain and establishing a stable hemostasis.
